RDMA/addr: Fix some cancellation problems in process_req()
Fix following problems in process_req() relating to cancellation:
- Function is wrongly doing another addr_remote() when cancelled,
which is not required.
- Make failure reporting immediate by using time_after_eq().
- On cancellation, -ETIMEDOUT was returned to the callback routine
instead of the more appropriate -ECANCELLED (users getting notified
may want to print/return this status, eg ucma_event_handler).
